Application filed July 21, 1910. Serial No. 572,955.

To all whom it may concern:

Be it known that I, CHARLES- B. K ne, a citizen of the United States,residing at Detroit, county of Wayne, State of Michigan, have invented acertain new and useful Improvement in Throttle Mechanism forAutomobiles, and declare the following to be a full, clear, and exactdescription of the same, such as will enable others skilled in the artto which it pertains to make and use the same, reference being had tothe accompanying drawings, which form a part of this specification.

My invention relates to throttle mechaprovements hereinafter describedand point ed out in the claims.

in the accompanying drawing,-l igure"l, is an elevation partly insection of an apparatus embodying my invention and so much of theadjacent parts of an automobile as is necessary to illustrateits'connection therewith. Fig. 2, is a detail view, mostly in section.

A, is the steering post. The steering post is cylindrical, and hollowfor the greater part of its length, it is adapted to turn in astationary bearing B which is supported in any usual way upon theautomobile.

C, is the carbureter.

T, is a throttle valve adapted to turn to adjust the area of a passageconnecting with the carburetor, to throttle the intake of the engine.

'6', is a lever upon the throttle valve T by which said throttle valveis operated.

R, is a rod pivoted at one end to the outer end of the lever arm 5' andsupported toward the other end at f by a lever arm L pivoted at b to theframe of the automobile. Toward the other end the lever arm L forks intotwo branches 6, e, which extend upon opposite sides and adjacent to thesteering post A. I

P, is a pedal upon the end of the rod R opposite to that which isconnected with the lever arm t.

S, is a sleeve surrounding the steering post A and adapted to slidelongitudinally thereon.

s, is an annular lug extending in a plane at right angles to the axis ofthe sleeve S.

There are two opposite slots E, E, formed through the walls of thesteering post A.

post A is turned by the wheel W through the side walls of h, 72,, arespiral slots formed in the head h .h The pin D extends through the slotsThe upper end of the rod F rests in the hearing at the upper end of thesteering post G, is a lever arm secured upon the outer end of the'rod Fby which said rod may be rotated.

The outer ends of the forks e, e, of the lever arm Lrest against theannular lug s of the sleeve S and contact therewith spring d.

The operation of the above described device is as follows :In theordinary operation of the steering mechanism the steering in the usualway, the ends of the forks e, a, sliding upon thesurface of the annularlug 8 without atfooting the throttle valve. If the operator wishes tosuddenly close the throttle valve, he presses his foot against the pedalP turning the throttle valve T by means of the lever arm t and rod it,the'lever arm L swinging so as to bring the forks'e, e, contact with thesurface of the lug s. the operator wish to partly close the valve T, hepresses his thumb or finger against the outer end of the lever arm Grturning the rod F and head H and acting the spiral slots are normallyheld in by the compression along the steering post A to rock the leverarm L, to operate the throttle valve T through the rod R and lever armt.

g, is a torsion spring acting to turn the rod 15 to bring the parts intotheir normal position when they have been manipulated to force themtherefrom.

What T claim is 1. The combination of an engine operating part, asteering post, a part adapted to slide lengthwise upon said steeringpost,

it, against the pin D to move the sleeve S ver resting against saidsliding part, and

I oted lever engaging against said lug, and a ver so that any movementrod pivoted to said engine operating part and said lever, said leverhaving a pedal connected therewith, for the purpose described.

4. The Combination of an engine operating part T, a pivoted lever L, arod R connecting said lever and said engine operating part so that anymovement of one will follow the movement of the other, a steering postA, a sleeve S on said steering post, slots in said steering post, a pinD extending through said slots, a rotatable head H in said steering posthaving a spiral slot h, engaging said pin, and means for rotating saidhead, the lever L resting against said sleeve, substantially as and forthe purpose described.

5. The combination of an engine operating part T, a pivoted lever L, arod It connecting said lever and said engine operating part so that anymovement of one will follow the movement of the other, a steering postA, a sleeve S on said steering post, slots in said steering post, a pinD extending through said slots, a rotatable head H in said steering posthaving a spiral slot h engaging said pin, and means for rotating saidhead, the lever L resting against said sleeve, and a pedal P adapted tooscillate said lever.

In testimony whereof, I sign this specification in the presenze of twowitnesses.

HARLES B. KING.

means for adjusting said sliding parts to different positions along saidsteering post, a pivoted lever resting against said sliding part, andmeans connecting said engine operating part and lever so that anymovement of said lever shall actuate said engine operating part, and apedal adapted to impart motion to said lever that shall carry it out ofcontact with said sliding part, substantially as and for the purposedescribed.

2. The combination of a throttle valve, a steering post, a part adaptedto slide lengthwise upon said steering post, means for adjusting saidsliding parts to different positions along said steering post, a pivotedlethrottle valve and leof said lever shall actuate said throttle valve,and a pedal adapted to impart motion to said lever that shall carry itout of contact with said sliding part, substantially as and for thepurpose described.

3. The combination of an engine operating part, a steering post, asleeve upon said steering post adapted to move longitudinally thereofbut restrainedfrom angular motion relative thereto, a part adapted torotate within said steering post, acam upon said rotating part withinsaid steering post engaging said sleeve so as to cause a longitudinalmovement of said sleeve when said part is turned, a lug upon saidsleeve, a pivmeans connecting said Witnesses:
